Usually I think of those as blasting mats. I remember as a child riding through highway construction zones around Peterborough and Haliburton, where they would demolish rock outcroppings to allow levelling and straightening the road. There were similar mats used there. I think they put them on top of the rock being demolished to prevent small pieces from flying off. I’d be a bit surprised to find they need to do that in downtown Kitchener however — even the deep excavation for the QNC at the University of Waterloo didn’t get anywhere near bedrock.
